Explanation:
<h2>(a).</h2>The density of a substance can be found by using the formula
From the question
mass of metal = 14 g
volume = 2.98 mL = 2.98 cm³
It's density is
We have the answer as
4.70 g/cm³
<h2>(b).</h2>The metal is not copper since it's density is less than that of copper.
Hope this helps you
Answer:
Explanation:
Hello,
In this case, for such formation of sulfur hexafluoride, the standard enthalpy of formation is -1220.47 kJ/mol (data extracted from NIST database). Next, we compute the moles in 10.0 grams of sulfur hexafluoride as shown below:
Next, for the given energy, we compute the total heat that is liberated:
Finally, we conclude such symbol has sense since negative heat is related with liberated heat.
Best regards.
